LUTHER B. DEMUTH, OF NEW PHILADELPHIA, OHIO.

Application filed April 2 1,

T 0 all whom it may concern:

Be it known that I, LUTHER B. DEMUTH, a citizen of the United States, residing at New Philadelphia, in the county of Tuscarawas and State of Ohio, have invented certain new and useful Improvements in Irrigating Devices; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This inventi on relates to an improved irrigating device which may be termed a sprinkler and one object of the invention is to provide an irrigating or sprinkling device having a rotatably mounted supply pipe provided with outlets throughout its length for directing jets of water transversely or radially of the supply pipe and having improved means for imparting rotation of the supply pipe in one direction against the action of resilient means holding the pipe against rotation and then permitting return movement of the pipe to its original position.

Another object of the invention is to so construct the means for causing rotation of the pipe against the action of the resilient means that the pipe may be caused to rotate comparatively slowly when turning against the action of the spring and then rapidly rotate when turned in a reverse direction by means of the spiing thus causing the jets of water to be thrown from the supply pipe in a very effective manner for sprinkling and irrigating.

Another object of the invention is to so construct this device that the means for causing rotation ofthe pipe against the action of the resilient means may consist of a bucket swung from a lever a 311 carried by the pipe and filled with water, the pipe being rotated as the weight of the water increases and the weight of the water when reaching a certain amount causing the bucket to tilt and empty the water thus permitting reverse rotation under action of the spring.

Another object ofthe invention is-to so mount this bucket or water receptacle that its center of gravity may be changed when so desired and thus the amount of weight needed to tilt it controlled, or in other words the bucket caused to tilt when a predetermined amount of water has passed into the IBRIGATING DEVICE.

bucket and the weight of this water rotated the supply pipe a desired amount.

This invention is illustrated in the accompanying drawings, wherein:

This sprinkler or irrigating device as it may be called is provided with a supply pipe 1 which is rotatably carried by standards 2 and will be of any suitable length desired, it being understood that an appropriate number of standards 2 will be provided according to the length of the supply pipe 1. This supply pipe is provided at points throughout its length with outlet nozzles 3 which extend as shown in Fig. 2 so that jets of water may be thrown radially from the pipe and thus trees, grass and other vegetation permitted to be sprinkled. This pipe is rotatably carried by the standards and. therefore it can be turned from the position shown in Fig. 2 in which the jets of water extend as shown to the position shown in Fig. 5 and then back again to the position shown in Fig. 2-. Therefore, the jets of water will be swung in the are of a circle but will not make a complete revolution. In order to normally hold the pipe in the position shown in Fig. 2 and yieldably resists rotation toward theposition shown in Fig. 5, there has been provided a spring 4: which has one end portion connected with an anchoring element 5 by means of a link 6 and .has. its upper end portion connected with a cable 7 which is attached to a semi-circular V 65 2. Th'e pipe 1 is provided with a branch pipe will be rotated, and the jets of water will be swungrin the arc of a circle and finally caused to extendfrom the pipe as shown in Fig. 5 instead of as shown in Fig. 2. In order to, swing the lever arm 9 down wardly, there has been provided a water bucket 11 which is provided with a bail or handle 12, the intermediate-portion of which -is offset as shown at 13. Links 14 have their lower ends loosely mounted upon the handle portion 13 and have their upper ends pivotally connected with the free end portion of the lever arm 9. Therefore this bucket will normally hang in a horizontal position from the free end of the lever; The arms of the bail or handle 12 have their lower ends pivotally connected with rods 15 which are slid ably mounted in sockets 16 which extend from opposite sides of the bucket. One socket at each side is-provided with a setscrew 17 which canbe tightened to engage the rod 15 and thus'se'curely hold the rod against movement and retain the handle or bail in the desired position with respect to, the bucket. Lugs 18 extend from the rods 15 and by engaging the depending arms of thebail limit rearward tilting of the bucket and prevent it from moving rearwardly out of a horizontal position. This bucket has its forward end portion extended so that as it fills, more water is positioned in the for ward end portion of the bucket and therefore as the bucket'fills, this forward end portion will gradually become overweighted and the'bucket will tilt forwardly to empty the water. By adjusting the handle rearwardly of the bucket, a less amount of water will be necessary in order to cause tilting of the bucket and therefore the pipe will not receive rotary movement to its full extent before the bucket is emptied and the spring 45 permitted to act and return the pipe to its normal position. -In order to through the nozzle3from which it will be ejected in streams or jets as shown in Fig.

spaced 1 maps? pipe 22 having a controlling valve 23 so that passage of water through this pipe 22 into the hose 24: leading therefrom can be controlled. This hose 2 1 is engaged by a clamp 25 adjacent the free end of thelever arm or bar 9 and is extended over the free end of the lever and carried downwardly and engaged by a clamp 26 having arms extending therefrom. and connected with the hanger links lt which are carried by the lever and engage the offset portion of the bail or handle of the bucket. VVate'r from the supply pipe 1 may therefore pass through the hose 24 and serve to tillthe bucket 1 thus supplying the necessary weight to swing the lever 9 downwardly and rotate the'pipe 1. As the water gradually fills this bucket,this turning o'f-the pipe Wlll be gradualand therefore the jets of water passing from the nozzle 3 will swing in such a manner that the water will be well distrib- V uted. hen the bucket reach-es the position shown in Fig. 5, water will continue to flow into the bucket until theweight of the water in the extended forward end portion overcomes the weight in the rear end portion. This bucket will then dump and the water will tlow'out of it. 'The spring 4 can then act upon the arcuate block 8 to swing the arm and bucket upwardly and return the sprinkler to its normal position. By. adjusting the rods 15 longitudinally of the bucket, the center ofgravity of the bucket can be changed and by means of the weight 18, a finer adjustment can be accomplished. It will thus be seen that if desired, the bucketcan be caused to dump sooner thanwhen the bucket is balanced as shown and the jets of water caused to have a shorter swing be fore the bucket dumps and the spring returns the sprinkler to its normal position.
